Extended Unified Campaign Install Question

[Enfilade]

I understand that I should install the Extended Unified Campaign mod in the following order:

SH3/1.4b;

GW;

NYGM Tonnage;

EUC Campaign.

My question is what about the two add-in files for NYGM Tonnage, the Battery Fix Mod and the Terrain Add-In Mod. Do I need to install these separately or are they now included somewhere in the above? I'm trying to avoid any duplication that might cause conflicts.
